We love St. Arnold's. We've been here on weekdays for lunch, Saturdays for group get-togethers and even for a rehearsal dinner in a private area.
The lunch always sounds simple, but it's a more gourmet version of whatever they're serving. And it's a ton of food! Most recently we were here for Memorial Day and had a delicious pulled pork sandwich, salad, chips, potato salad.
If you're going with a big group on a Saturday, make sure someone in the group goes early to save a spot in line if you want a table. Otherwise, bring lawn chairs or a blanket. Bring games and food, and if you're trying to save a whole table for people who aren't there yet, table cloths work wonders.
