From my experience, it's somewhat sacrilegious to declare that you just don't like smoked meat around here. Every single person I've told had that look on their face like I just killed their cat.
Luckily, The Main has things other than smoked meat sandwiches, unlike their neighbor Schwartz's. I heartily recommend the pierogies - or as they're called on the menu, vareniki - with sour cream. Ask for them fried! (Note to the Russians/Ukrainians/Belarussians reading this: they aren't actually vareniki, they are more like the Americanized pierogies.)
The atmosphere inside is a little greasy spoon-ish, but their outdoor terrace is absolute dynamite when you're in need of a greasy snack after drinking all night.
