It was 11:30, I was near Central and Camelback and popped into a local restaurant that closed at midnight but the kitchen was already closed at 11pm.
So I headed a few blocks east to 5 and Diner and was so glad that I did. The place was packed, but only had to wait a few minutes to get a booth. I did notice a lot of teenagers/under 21 crowd but it was a Friday night and this place is open 24 hours, no harm, no foul.
My burger and fries were delicious, nothing spectacular but exactly what I expected. My wife who is a vegetarian, was able to substitute the beef patty for a black bean patty and she was impressed on how delicious it was. The vanilla shake hit the spot also, very yummy. Only complaint was the onion rings that accompanied my wife's burger were a bit soft and not crisp.
Bottom line, I'll be back on the late night sometime in the near future, I'm sure of it!
