Gina is considered one of Tel Aviv's top falafel stands, and the proof is in the lunchtime crowds. The pita bread is fresh, and the hot falafel balls are slightly greenish because of the parsley added to the mix. Be sure to try the tahini. Sunday-Thursday for breakfast, lunch and dinner. Reservations not accepted. $. No credit cards. 22 Shocken St., Tel Aviv. Phone 683-1123.
