Basil Sausage Pasta
Jeff K.

I am somewhat of a Thai fanatic/guru and when I saw the crazy menu this place had, I had to order. Pad Thai spring rolls? Genius and a must try. The Basil Sausage Pasta is so good and bring a napkin because you will sweat. Can't wait to try in person.

I was excited to try Black Ruby on my recent trip to Boston and made a res for noon on a Saturday. Definitely would recommend making a res as there were only bar seats for walk ins when I went. We shared the Tom Yum Shrimp Pasta and Massaman Curry Burger. Both were pretty good but the pasta was delicious. Loved the spicy creamy tom yum inspired sauce that paired well with the fettuccine pasta, shaved parmesan, and tender shrimp. The sauce was really flavorful with a nice spicy kick that was mellowed out with cream. So so good and very addicting. The burger was ok but came out a little lukewarm even though it was sent out super quickly once we ordered. The curry sauce was yummy but the burger itself was a bit dry and bland and the fact that it wasn't hot didn't really help the flavor. I also got the Thai coconut coffee which was ok the sweeter side but nice to have to drink alongside the pasta. Would come back just for the pasta and maybe try an app or 2. The burger was a pass for me but definitely worth a try for creative Thai fusion food in Cambridge.

I came here for dinner recently and had a lovely time! If you're going around peak dinner times (6-8pm), I highly recommend reservations. Service was really quick and polite. I got their lemongrass shrimp ceviche and their green curry grilled beef rigatoni + their mango sticky rice colada to drink. The shrimp ceviche came out beautifully presented and a good portion. While I wish there was a bit more of the lemongrass flavor (I didn't really taste the lemongrass in it at all), it wasn't bad. The green curry rigatoni was really creamy, rich, and such a delicious fusion dish. However, I did think that their steak was a bit too tough and overdone. Their mango sticky rice colada drink was SO good. Overall, absolutely amazing and I will have to come back to try their burgers!

mango sticky rice sundae ($13)- i'd be back just for this!! so good

Walked in on a Thursday 7p, and it looked busy with a few tables open. This establishment clearly displays a sign restricting guests to 70min. Street-side metered parking is easily accessible, and you are just steps from the Avon Hill mansions! Vibe: relatively casual with bar, dining, and outdoor seating options. promptly greeted, seated, and served. Food 4.5/5: - I applaud them for their ingenuity integrating Thai flavors into American fare! Everything was very accessible. - I had the crispy basil burger ($20): minimally spicy, perfectly juicy, nice runny egg, not overpowering in flavor but just what I was hoping for, would get again - my friend had the massaman curry burger ($20) which had more cinnamon than I was expecting; solid burger but not genuinely massaman flavored - we shared the larb parmesan fries ($12): great potato fries with spicy larb sauce, but not anything to dream about - real star of the night was the mango sticky rice sundae ($13): I've had my fair share of these; and this was among the most satisfying ones I've had We didn't get drinks, but they looked incredible. In short, if you're looking for a good, $20 burger with a Thai twist or a delicious mango sticky rice in a casual atmosphere, Black Ruby has got you!

Larb Parmesan fries

Classy sleek yet casual ambiance for lunch. Service was friendly and we were seated quickly. We got the massaman burger and the chicken satay sandwich, as well as the larb Parmesan fries and mango sticky rice sundae! The massaman burger was juicy and soaked with all the flavors in the sauce. The burger buns were very fluffy and the chicken satay was well flavored. The fries were nice and crunchy. Solid meal for a reasonable price!

Thai Iced Tea & Thai Iced Espresso Martini
Brendon T.

Black Ruby completely exceeded my expectations. The idea of Thai-American fusion with craft burgers and pasta sounded intriguing, but the food was genuinely impressive. Our favorites were the Mussels in Red Curry Rice Wine, Red Curry Bolognese, Massaman Beef Burger, and Mango Sticky Rice. Each packed with flavor and executed beautifully. The Thai Iced Tea was also excellent, while the Thai Ice Espresso Martini just wasn't for me. The staff were incredibly friendly and welcoming, and the restaurant itself was clean, cozy, and inviting. The only downsides were that they had run out of their sourdough brioche buns, which I was excited to try, and reservations were tough to get as we had to book about a month in advance. Even so, it's easy to see why this place is so popular. I'll definitely be back and hopefully try some of the burgers with those sourdough buns next time.

I have to admit, given all the hype, I was expecting a bit more from Black Ruby. My friends and I came on a Thursday night with a reservation, and the restaurant was packed. Now, I suspect this might due in part because of the hype + location + thai/american fusion flavor, but even with a reservation we still ended up waiting about 30 minutes to be seated. Unfortunately, the service throughout dinner wasn't much better. Between the three of us, we ordered the scallion fries (which, for anyone wondering, aren't actually fries tossed in scallion oil or dressing), the fried calamari, the red curry Bolognese, the green curry pasta with steak, and, of course, the much-hyped Massaman burger. The fried calamari was probably the weakest dish. It had a fishier taste than I expected, and the breading was fairly greasy and tended to fall off. The scallion fries were good, though not especially memorable. Of the entrées, we preferred the green curry pasta over the red curry Bolognese, though both became a little heavy after a while. The Massaman burger was solid, but not quite the standout I was hoping for. Across the dishes, our biggest takeaway was that the curry sauces all leaned fairly rich and salty without much contrast. A little acidity or citrus would have gone a long way in brightening the flavors. Overall, Black Ruby was good, just not quite as memorable as I expected. Nothing we ordered really wowed us, but it's still a perfectly solid spot if you're in the area. I'd be open to coming back, though I'd probably try some different items if we were ever around Harvard Square.

Larb Fries

Fries were good, the sauce they came with was quite unique. The burger flavor was good and very filling. The sauce the burger came with was yummy but the taste became boring after a while. I really loved the pickles in the burger though! Would come back again, but probably not for the same burger.

When I was walking into my reservation for 7:15pm there was a long line of people waiting outside (like 10-12). I was looking to go here for a while and thanks to my friend Erin, it came back into my radar. It's giving sleek but with character. Visually reminds me of the design of Krasi.The servers really are on your butt when it comes to ordering and everything to the point where I was like can yall chill please lol. In the first 10 minutes we were there, I swear they came to the table like 3-5 times. They are really trying to get people in and out which I get but maybe be a little less obvious about it. Otherwise, service was respectful and nice. The presentation of the drinks was also really nice. I got a pink float and that was like strawberry milk with a nice scoop of ice cream. It was so fun and childish I made sure to have every single sip. The person next to me even asked what I got. My friend got the thai martini and she said it was delicious and couldn't taste the alcohol which for her is dangerous lol. The burgers, which are what they are known for, were a site to see indeed. For the curry burger it essentially is a pool of curry with a split in half burgers sitting in it. I was afraid that the buns would be soggy and to my surprise it wasn't and was delicious with this nice mini crunch from the topping. I actually preferred my burger which was a Big Crunch and juicy with pickled mustard greens. I also realized my burger had curry sauce in it too. Special mention to the scallion fries, what came out was not what I expected but it was one of my favorites. We got two things listed as spicy on the menu but did not taste spicy above a level 1 or 2. In addition, the menu online does not list their drinks lol so make sure to look at the last page for dessert and the milk floats. The restaurant is right in Porter Square where there are also SO MANY other great options but would go again for food and fun drinks.

I had such a lovely experience here. I didn't have a reservation but was surprisingly seated instantly. The restaurant was on the smaller side and has been a hot commodity so I really wasn't expecting to land a seat on a Sunday night. The staff was super friendly and helpful with the menu, I had a couple questions. After speaking with the waiter I landed on the Massaman burger and chicken sandwich. Both were seriously UNREAL. I cannot stand dry beef or chicken and the meat itself was so moist. Once combined with their sauce...life changing. I cannot wait to go back here.

Green Curry Cream Sauce Pasta

Thai Fusion? I am often skeptical when it comes to any asian fusion spots, but Black Ruby...does it VERY well. I was honestly blown away. The Massaman Burger, y'all already know that's why I came. Is it worth the hype? Some people are saying this is the best burger in Boston. Curry... and Burger? Somehow, someway... this works extremely well. That's a real good burger. I'm a huge texture person so the crunch was perfect. The curry wasn't overpowering at all. The green curry pasta was so good! The perfect spice level and the thickness of the curry stuck to the pasta perfectly. However, the steak might've been a little overcooked, in my opinion. Still good, though. Reservations are recommended, but walk-ins are allowed. I got lucky when arriving! Perfect spot for date night, and the drinks are sooo good. I got the thai tea martini and it was yummy. I'm not a big fan of an old fashioned, but it was pleasant. This might be the only place I'd voluntarily drink one.

Came here on a Sunday for a later lunch and the place was pretty empty. Interior was sleek and modern with wooden finishes with plenty of lighting from the big windows by the front. Menu had a good selection of entrees which I shared everything with a friend rather than order separately. Service was solid and relatively quick. Food came out in a reasonable manner and everything tasted great - Thai tea was yummy, burger was delicious, fries were so well seasoned, and the pasta was great along with the dessert. Only complaint is portions - definitely small for what you paid for. Overall, we had a solid meal and left feeling very full. I wouldn't mind coming back, but it isn't a restaurant I'd be a regular out due to its price.

Really interesting and tasty menu. I thought the drinks would be too sweet but they were quite good. It's a busy place but you can get a reservation. It's a little tricky if you need to wait inside. The servers are on top of things but efficient as are the seatings but it was a good meal!

Would not have thought such a good and what feels very authentic. The staff were nice and the ambiance was chill. Low key in the best way.

Very disappointing, with one standout dish…read more Boonnoon Market was probably the most disappointing food I've tried since moving to Somerville. Unfortunately, most of what we ordered fell well short of expectations. The green curry was particularly unpleasant. The sauce had a strong flavor reminiscent of unwashed canned bamboo shoots, and the dish was much more like a thin soup than a curry. At $16, I was disappointed that it didn't come with rice and had such a small amount of chicken and vegetables. The satay noodles were another letdown. They had a strange flavor and an extremely gummy texture that made them unpleasant to eat. The karee puffs were decent, although quite dry, and would have benefited from a dipping sauce. The one genuine highlight was the pla lui suan (deep-fried mackerel). The breading was flavorful and satisfyingly crunchy, and it was the only dish I would genuinely recommend based on our experience. Overall, I left very disappointed. One good dish couldn't make up for the lackluster flavors, unpleasant textures, and poor value of the rest of the meal.

This is my FAVORITE Thai place in all of Cambridge and probably Boston. I so so recommend it, I'm…read morebaffled at some of the lower ratings. I've gotten lucky with walking in but they have enough seating for one to generally be able to snag a table even around dinner time. During the summer, they have lovely outdoor seating! I've gotten take out here once and the food holds up well. Now onto the food... - drunken noodles: occasionally these are very spicy and occasionally they are appropriately spicy. They are always so excellent and the noodles are bouncy and chewy! I usually get this with pork. - pad see ew: this is my favorite Thai noodle dish and it's no exception here. Not as spicy as the drunken noodles but just a massive portion of filling noodles, chicken/tofu, and Chinese broccoli. There's something about the way they do the sauce here that is just so savory and delicious. It feels less greasy than it usually does at other Thai places, which I really like - pad mee korat: my friend always get this and raves about it. I felt like it was worth sharing that this comes in a huge plate and was finished completely. They have a lot of variety in dishes!!
