Depends on how hungry you are. Beef suya is awesome - it's grilled lean beef topped with a spicy powder that has a lot of peanut in it and red onions. If you're still hungry after a skewer of that, try egusi. It's a thick stew made with crushed melon seeds, eaten with fufu - pounded starchy yam, steamed- or banku - pounded green plantains, also steamed. It can be spicy but it's delicious.

Snack Mania across from Seabra's does a bunch of nifty looking quick snack foods and coffee. Haven't been myself, but it looks hella legit.
