I'm a long time fan of Sonic. Just the drink possibilities are awesome. I recommend a Watermelon Limeade (that's a limeade with watermelon flavoring) or a chocolate coke.
U can never go wrong with tots (with or without chili/cheese/onions) - they are way better than any french fry ever concocted! The "new" hot dogs they have here are pretty tasty. I had a Chicago-style dog, and it was piping hot with a snappy casing as you bit into it. I'm not gonna abandon a true Vienna Beef dog joint for them - but it's nice to know they are almost as good! Maybe next time I stop in I'll see if they can do a foot long this way - that would be awesome, although there won't be a poppy seed bun involved, and that's a shame.
Sonic, are you listening?? You could create AND corner a market with footlong ChiDogs - but you gotta have the poppy seed buns!!
Check their add-on list - you can add a lot of things (including green chile and jalapenos) to just about anything, and that is just one more bonus that sets Sonic apart from the rest of fast-food corporate America.
One of my fave things about Sonic is that the carhops rollerskate - alas - even Sonic seems to be slacking off on this. It should be required to have ALL hops on skates. I do give them props for hiring people that can actually count change correctly! It's hard to find a waitress or cashier these days that can subtract $9.91 from $20 in their heads. Sonic is keeping mathematics alive!
