Original review, Feb 3 07: First of all, Zemam's is deserving of a much higher rating than the 7.6 it has now. If you look at the five ratings it was given, it's all nines and tens -- except for someone who registered under the name "Anonymous" and rated Zemam's a one. I wish people who gave low ratings would write reviews to explain what's so wrong.
I went here tonight for the second time. There is a good variety of vegetarian/vegan dishes to choose from, and everything is excellent. Some things are extremely spicy, though, such as the chickpeas and spinach/potato dish. You should probably ask your server which dishes to avoid if your palate can't quite handle the heat.
My favorites are the cabbage, lentils, and split peas. All mildly spiced, flavorful dishes.
My only complaint is that the "sampler" is priced with the assumption that you'll be ordering higher-priced meat items. You're not getting as much value if you order all vegetarian dishes. I sort of wish they had a separate price for vegetarian samplers.
Updated review: This is currently my favorite restaurant in Tucson. For two people, I like to get a vegetarian sampler (which is now a menu option that is lower in price than a meat sampler) and a full, heaping serving of the split peas. I don't know how they make those split peas so good, but I could eat them every day. It's also possible that I've trained my palate in recent years, but these days the spicier items haven't been bugging me. I love the cabbage/carrot/potato and red lentils, too.
