Food Galleria 212 Main St (203) 846-6810
Russian supermarket, very interesting stuff. I'm crazy about Babaevsky 75% cacao dark chocolate bars. They do hot food, but are unable to say when. prepared foods can be bought chilled from the case facing the back right hand corner of the store (when entering the door). Interesting honeys, including buckwheat honey and legendary (and expensive) Bashkirian organic honey, widely said to have super antibiotic quality
Latin Flavor & Fish 102 Wall St (203) 866-0707
Didn't have the fried fish, but their steam table latino food is absolutely primo. Best rice I've EVER had in a Latin restaurant (pigeon peas and other stuff mixed in). Excellent chicken. Nice owner.
Mi'casita Restaurant & Bakery 177 Main St (203) 845-0202
Columbian bakery, very good empanadas, but killer (very potato-y) chicken empanadas when they have them (more of square-ish shape)! Also, I like their arepas de chocolo (fresh corn sweet arepas) a lot. Pan de bono is very good, not great. Nice people.
Very near to Latin Flavor/Fish is "Atlantic Meat Market" (110 Wall Street, (203) 838-2347), a butcher shop straight out of a time machine. I didn't go in, but hear they do sandwiches for lunch.
Been meaning to try Cafe Galicia (83 wall st 203-831-8184), which is supposed to serve very authentic peruvian/ecuadorian.
