First of all, the food is always fresh, always delicious. You would pay just as much at Chili's for a dish that was frozen and reheated, and it would not be nearly as tasty. Also, they have awesome happy hour deals.
The food is elevated, but far from pretentious. Both foodies and less adventurous eaters will find something they like on the menu (They have a kid's menu too!). The brunch buffet is also delish, and at $15 a super deal, I think. I've been here 5 times, and I've never had a bad meal.
Secondly, the service is top-notch; waitstaff is exemplary and very accommodating. Plus, it's very easy to make a reservation on their website, and I've never had to wait for a table with a reservation -- one of my pet peeves!
Finally, it's perfect for any occasion. We have brought our 11 month-old here several times and not felt uncomfortable or out of place...parents you know what I mean! It's equally great for a Girls' Night, date night or a birthday/anniversary dinner. You could wear shorts and flip-flops there or slightly dressy apparel and not feel awkward either way.
That is why Jack Allen's is our go-to spot for a great meal anytime. Try it, you'll like it!
