Got off work in for happy hour so I thought I would try Fat Cats in Tremont. Kind of off by itself at the North end of Tremont, but there is a great view of downtown. The decor is relaxed, with some funky art in a nice old school building, with a compact covered patio next to the small parking lot.
Sat at the bar, service was friendly and prompt. The Happy Hour menu is diverse and has some nice choices. I choose the Mussels, the Tempura Shrimp and the Sweet Potato Fries. For $5 you get about 10 nice sized mussels in a nice garlic broth; not a huge portion but very tasty and well prepared with a perfect crostini to soak up the extra broth. The sweet potato frites were a nice sized portion of various sized pieces of sweet potato lightly battered and fried and then served with an excellent tomato jam. The best dish was the tempura shrimp which were two jumbo tail on shrimps with a crunchy batter served with a sweet and sour sauce that made the shrimp sing. The portion is filling and the taste is excellent.
Overall the portions are not huge, but the food is very good. Worth stopping in if you are near Tremont.
