Ordered up a chicago dog and fries.
I found it to be a tad heavy on the mustard and the bun was slightly stale (slightly...not a lot stale). Tomatoes were sliced a little thin and maybe not quite as fresh as they could be.
Fries were fries. Nothing special, but not bad either.
Having said the above, it was pretty good and worth a return trip.
Not a 4, but not a 3 either. Call it 3.5.
