According to a local we talked to Marv's has the best fish&chips around. Whether that's true I…read morecan't say, but I can say it was just ok. We arrived around 5:00 on a Saturday evening to an empty parking lot and dining room, and no other diners arrived during the hour we were there.
I had the fried fish and clams special and the wife had the fish&chips. Both served with french fries and coleslaw. The fish and clams were fresh, though I wasn't impressed with the batter. The fries were of the generic, frozen variety, dry and uninteresting. The coleslaw was a ludicrously small thimble-sized portion but was ok, with a slightly tangy, mustardy dressing.
They serve beer and wine here only, no cocktails. But beer and wine lovers alike would be disappointed. We both wanted red. The waitress didn't know what kind it was and offered to check. We saved her the trouble and said whatever they have would be fine. It turned out there wasn't enough for two portions so she split what was left into two glasses. The wife decided to have a white instead so we combined the two reds into a glass for me and the white turned out to be a pinot grigio, her new favorite. My red, not so good. The bottle had clearly been opened too long. I guess not many wine drinkers here.
For beer, only big-name brands, both Canadian and, surprisingly at this time in Canada, American. No small craft brands whatsoever.
The ambience was typical diner, no complaints there.
The best part was dessert, which we hadn't even planned to get. At the end of the meal two were brought over, without asking and at no charge. Since they were going to be closed for the next 3 days I guess they didn't want to waste them. A peanut butter cheesecake and a chocolate cream pie, the latter which was enormous, almost two portions. Both surprisingly delicious. We only tried the pie while there, taking the cheesecake home, and thanked her and complimented her on the quality. They were both made in house by the chef. The cheesecake, which I enjoyed over the next two days, was so good I've resolved to try this more often, not being something I normally order.
So, an enjoyable experience overall but I'd probably research other options if I find myself back in Yarmouth.
