Nigerian Food in Austin
Check out T's Cafe in Pfluegerville. (if it's still in business?)
I'm not sure if this place is still in business as I last visited about 2 years ago. I think this was the first time I'd ever sampled Nigerian food and it was really pretty tasty stuff. Most of the authentic Nigerian menu items (they served burgers, too, but T himself is from Lagos) were similar to a beef or veggie stew. I had Peanut Soup and it had a very thick consistency and was mildly spicy.
I would go back, but I'm not in that neighborhood very often
