    The oxygen bar and menu
    Lindsay J.

    O2 Lounge is a fun spot in Lake Geneva! There are so many components here...The name screams oxygen bar, but really I think they are a boba bar. My son hates boba, but loves a good Horchata drink. O2 had the best Horchata! You can get any of the drinks with or without boba, and they have the cutest cups with the sealed lids. He gets the horchata sans boba and loved popping the straw through the seal. There are always four choices for frescas, tea drinks, that you an add boba to if you like. After the drinks, you have the oxygen bar. There are 6-8 fragrances that you can choose from. The menu shows six, but they definitely have a couple flavors beyond the menu. The oxygen is expensive, but it is a fun experience and refreshing. Then, they have pastries and alcohol. Crazy combinations, but they are catering to parents waiting for their kid to finish their boba or oxygen time. Again, expensive, but a great novelty location in LG!!

    I saw bubble tea so very much wanted to try it. It was odd at first to see it called the O2 lounge so I still wanted to try this place anyway. To the right as you walk in is an oxygen bar with a rainbow of flavors to add. Straight ahead I saw 4 pots and the gentleman was kind enough to explain that every day they carried 4 different fresh fruit drinks that was available among other flavors to make bubble tea for the day. The horchata drink is always one of the 4 batches each day and the fruit drinks will vary. I love horchata so decided I wanted boba in it and had it blended like a smoothie and it was delicious! There's room to sit and drink and they serve alcoholic drinks as well from beer and wine to specialty cocktails with fresh fruit drinks, pineapple and coconut water too. They carry tea, coffee and hot chocolate. They make snow cones and smoothie bowls. It's a great place no matter what your mood. You gotta try it!

    Taro milk tea with regular tapioca pearls

    Decided to take a day trip to Lake Geneva to try a Thai restaurant called Sabai Sabai. Afterward we wanted to grab some bubble tea. The O2 Lounge was a 3 minute walk away, it worked out great. I ordered the Taro milk tea with regular tapioca pearls. The tea was great, the pearls were fresh/tender, and the service was very pleasant. We did not get the chance to try the oxygen station, which looks intriguing, but the tea was worth the trip anyways.

    We came here last night. I really liked it. The owner was very nice and attentive. He even provided us with some horchata water samples. It was delicious! We did a 20 Mn O2 with eucalyptus ( I had sinus ) and it really helped, now I'm way better than yesterday.

    The oxygen is fun! Lots of fun things to do and fun drinks. Enjoyable experience! There's a new studio upstairs and designer bags!

    Got the coffee latte with caramel. Somehow does not taste like coffee, milk, or caramel. Very overpriced

    Great service! I loved the design of the place, it was super cute. The acai was a generous portion,…read morewith unique toppings and one of the best açaís I've ever had!!

    After Pilates we went to get two small smoothies when walking by--first, they are very expensive,…read more$10 each. We also tipped well on top of our drinks. We received both and they were not a smoothie consistency at all, one in particular was extremely watery, not filled up all the way, and not very cold. Not a super huge deal at all as it can be remade. We asked a female employee to remake them or just reblend with ice. She was VERY irritated about it, took five min to reblend the most watery one and left a large portion of the smoothie in the blender because she didn't put it in a larger cup to account for the ice that adds volume. She refused to blend the second one at all with more ice saying "it's supposed to be that way" and was super rude to us, like more rude than I have experienced with an employee in a long time! We were polite and reasonable with our request. I have been a barista before and have made many smoothies and fraps--I can't express how easy it is to simply remake a drink or at the very least add some ice. It didn't warrant at all that kind of reaction... especially for $10.50 each and after tipping well. I'm just so stunned over that interaction. Very put off by that experience as locals! It's a great location next to Pilates right downtown but I can't imagine coming back if 1) the smoothies ARE supposed to be like that 2) they are so expensive 3) the staff is unaccommodating and rude. I will say the young guy who was on the register was very nice though although he is the one that made the drinks. However it did get busy and the female staff member was not helping him at all. Again... not a big deal on his end at all, things can be easily remade but we should not be treated with such hostility for a reasonable request.
