Jax is quickly becoming a happening place
House of dog a fleishig restaraunt opened a few weeks ago and the food is pretty good. There is also a milcihg takeout called tomato crush which opened a few months ago. He is cheaper and the food is supposed to be pretty good.
Etz chaim is a regular Ashkenazi shul and their minyanim are very punctual. Minyan at chabad is much more touch and go and I don't know how often they actually have 10.
Near the shul/food is a ramada and Laquinta but plenty of other hotels are nearby.
Feel free to reply or pm with further questions.
