U District on a Monday night
There are lots of ethnic places on the Ave, but nothing is outstanding in quality. Although I do like Falafel King II on 50th (around the area already mentioned above). Caspian Grill (if they're still around) serves interesting Persian, albeit a tad expensive. A little west on Roosevelt there's Taste of India, while not top notch, is certainly the best Indian food in Seattle proper (and most probably the Tri Cities) - although if you have to have Indian food, I'd suggest trekking across the lake.
Driving or bussing a couple minutes on 45th to the west side of I-5 will get you higher quality stuff. Joule (Korean/French fusion) is definitely worth a trip. There's also Kozue and Musashi (cheap plentiful Japanese), Tutta Bella for Neapolitan pizza, and Kabul for Afghan.

Also in that westerly direction, find Perche No, where a trippy happy hour can be had late in the evening. The staff made us members of the family in about two visits. The fresh pasta is killer and flavor is always out front. OK, so the cordiality of the place makes us kick back, order another plate, have another round, etc. The last time we were there, it was probably $75 for two of us, but worth every penny for a lovely evening of serious decompression, though we could have left satisfied for half that. Don't be surprised to be engaged by clientele. It's that sort of place.
Bizarro Italian Cafe was great once, though habits change and we haven't been lately.
Tutta Bella is spotty, especially in service, but the pies are sort of passable. We really enjoy the Solerno (think Caprese, extended with Romaine) Pizza Ensalata. It's a crisp, cool salad atop a freshly baked pizza crust. In summer, there is nothing better.
Pacific Inn, on Stone Way has good F&C, grilled Reuben and taps.
Paseo, on Fremont: The whole menu is a big winner and a bargain.

Corner of 50th and the Ave and northward.
Pam's, Chili's, a Hawaiian place, Mandarin Chef (I'm not a fan, but I know other's are), etc.
All the way up the Brazilian place that's almost at Ravenna.
I'd say just drive (or walk) in that direction and see what intrigues you.
If I had to pick one, I'd go with Pam's (Caribbean). But the options on that strip abound. All are at least "pretty good".
