Hennessey's is one of the newer restaurants that downtown Vista has to offer. The food is great. They offer breakfast, lunch and dinner and a full bar. Tuesday's are Two Timing' Tuesday's where you can get two hamburgers for the price of one. They aren't your typical burgers, they are "gourmet." They have the Mexican burger that comes with Cheese and Green Chili's or the Barbecue burger to name a few. They are all delicious. On certain nights they offer comedy and live bands. This is a fun place to go and eat.
