It's Denny's so what can I say? It's fine. It's not great but you know what you're getting when you go to Denny's.
If you've never been to Denny's then crawl out from your rock (jk) and go. The food is pretty good and the prices are reasonable. The service is mediocre but our server was hustling and I appreciated it.
I didn't really enjoy my hash browns b/c they seemed under-cooked to me.
Do I recommend Denny's? Not really but I still go once a year b/c they're reliable and conveniently located.
