Jac's is sort of an enigma. When you go you know the food and service will be good but you never know what you may get as far as the other diners. It looks like a place you would expect business casual and some people seem to realize that but others may show up in cut off shorts, T shirt and flip flops. You may get lucky and get there on a night when people that are more reserved and conscious of others are present or you may get people that should be at a fast food chain, loud and obnoxious and their equally loud kids. If you choose to eat in the patio area beware they allow smoking and nothing ruins a meal faster than having to smell a stinking cigarette. I never could understand how a serious restaurant could even consider allowing smoking anywhere. We had high hopes for this place when it opened and continue to eat there at least once a month because the food really is good ( we recommend the salmon Oscar) along with the service, the patrons though sometimes leave something to be desired.
