Great custards!!! Ah their rootbeer floats are amazing. So simple but so good! The food is good quality, pretty tasty when you're hungry but not anything extraordinary.
Nielsen's has a very wholesome, kinda 60's retro feel. The restaurant was clean, and the high-school age employees were attentive and polite if not very experienced.
The last time I visited, I ordered a vegetarian grinder and the waitress asked me if I'd like the "finer things in life" on it. I said yes. Turns out the finer things in life are slices of warm turkey breast meat. Little surprising for a vegetarian sandwich, but a good surprise!
I would definitely recommend at least trying it out!
