This McAlister's at the Arboretum seems to be a bit smaller than most (more narrow). I stop by every month or so to take lunch to my folks house. My typical order includes the New Yorker (Corned beef, pastrami, Swiss and spicy brown mustard on toasted rye) with a side of their potato salad - I love their potato salad. The sandwich is good with well flavored, tender deli meat. I also usually get a nacho basket for us to munch on too which is Ro-tel cheese dip and tortillas (hold the jalapenos, please). The dip tastes like it comes out of a jar and the tortillas taste like they come out of a bag, but this is a sammich shop, not a mexican restaurant, so I don't expect perfection. It's tasty and the dip is always nice and hot (hot temperature wise, it's a medium heat for spice).
And their sweet tea is YUM! I order half and half so I am not drinking a gallon of sugar, but it is SO good.
I usually go prior to 11:30 on a weekend, so there isn't a crowd. The employees are friendly and the to-go order is usually in my hands within minutes.
