Where to go eat in Tucson? Lots of great places! Let me take you there...
First stop: Zemams Ethiopian Restaurant, the one and only Ethiopian eatery available in Tucson. Ethiopian food traditionally consists of spicy vegetables and meat dishes (but no pork) served atop injera, a large sourdough flatbread. Also, patrons are expected to eat with their (right) hands, not with utensils. Similar to Chinese food, the dish is served "family style", meaning everyone share and eat from the same plate. So, be sure to wash your hands before dipping in!
Second stop: Taqueria Juanitos Mexican Restaurant for authentic Mexican food. It is a small, casual restaurant. The picture shown here are two different pork tacos with two different kinds of hot sauces. While you are there, also order the "Horchata" Mexican drink. It is an iced milky drink with a hint of cinnamon and vanilla taste. Very refreshing to drink, especially during summer time. One of my Mexican coworkers (thank you Maria!) introduced me to it a while back and I have loved this drink ever since.
Third stop: El Cubanitto Restaurant for Cuban food. It is another small, casual restaurant. Here is a picture of black bean, plantains and pork. The pork was a bit too dry for me but the plantains were excellent - soft and carmalized just the way I like it. What's interesting is the restaurant's decor. On the right is a long wall of baseball bats, on the left is a life-size skeletal of Fidel Castro!



Fourth stop: Athens on the 4th Avenue, a spacious, classy restaurant serving Greek food. Be sure to order the flambeed cheese. It is a bit salty so you should eat it with the accompanying pita bread. Do try out the appetizer plate with olives, feta cheese, eggplant spread and cucumber with home-made yogurt. I especially liked the yogurt, so creamy and refreshing. Got a sweet tooth? Also try the desserts.
Fifth stop: Takamatsu Japanese (and Korean) Restaurant. This restaurant offers Japanese sushi, teppanyaki, and even Korean food. The teppanyaki offering is very similar to Benihana. They start you off with soup and salad. Each patron gets a dish of ginger sauce and mustard sauce. Then the chef cooks in front of you, occasionally entertaining you with some showmanship (the regular fire, volcano, etc). The teppanyaki food at Takamatsu is all right. I personally like the Benihana better because Benihana seasoning is not as salty. But if you like rich, soy sauce taste, you should try Takamatsu.
