This place sucks. I debated giving it two stars, if only because it's the only vegetarian restaurant downtown, but I don't want this place on the front lines of what vegan and vegetarian food represents.
For one thing, the cafe portion looks like a church basement, and a dirty one at that. Floors are scuffed, there are boxes everywhere, the tables aren't wiped, and the kitchen area looks miserable.
They offer different pre-made daily specials (the day I went they had a fried rice dish, along with some kind of panini), none of which can be modified.
We ordered off of the regular menu (which is confusing and doesn't label what's vegan). We had a veggie burger ($5) and also a vegetable burrito ($5). Both were awful. The veggie burger was a Boca patty that they literally microwaved in front of me and then slapped on a bun. The "burrito" was a cold, clammy piece of tortilla with soggy, steamed vegetables. No salt, no spices, no seasoning of any kind.
The service was terrible: unfriendly; disorganized; and slow.
I recommend staying away from Kramer's if you enjoy the taste of food, or if you're looking for a good vegetarian/vegan experience. This one would turn you off immediately. Go to Karyn's on Green in Greektown instead.
