Mmmmm. I love that place, including the incredible tea. My favorite is the all-you-can-eat platter of everything . . . and tea! 
For smell . . . many spices and aromatics (such as from onions and garlic), after you digest them, are in your blood. So, you can't wash off the smell. It is with you until your liver metabolizes it. 
That's the "Ethiopian feast" which sounds like an oxymoron. That's what we always get but we add the lamb and salad. My wife is a big fan of lamb, the best of which, our experience, you can get in the odd little corner called Iceland. Anyway, I reckon they've got a good business model, based on that menu. It takes all the complexity out of their cooking. You make ten pots of stuff every night and get good at it. Everybody orders the feast. The kitchen knows what to do and just adjusts the volume based on experience and night of the week.
Anyway, if you're ever in town, dinner at BN is on me. Just let me know. You can probably teach me some tactics. I think I've mastered the 109 dive, fire, zoom, roll, dive repeat routine against turnier birds with an alt disadvantage but could use a little help learning to reverse the situation against mr. Spitty when he's co-E.
