This review is based strictly on their burgers.  Why?

I had just downloaded the Yelp mobile app and Harlow's was among the top burger search results for Tempe.

I know it's a great breakfast/sandwich/diner type place, but had never thought of it as a burger destination, until the Yelp mobile results.  So I headed on over.  Here's what I found:

It's not a burger destination.   

They offer 5 or so, starting with a basic burger, then different variations based on toppings... green chile, texas chile, bacon focused, etc.  I kept with the basic, plus cheese.  For $8 you get the basic burger with fries, and the variations bump it another dollar or two.  Drinks are extra.  

The menu said theirs were char grilled, but I think they are steam table cooked - no char or smokey taste on mine.  Likewise, I appreciate the regular menu featuring a lot of local product sources,  but I'd guess these are from a frozen patty national vendor.  It wasn't bad, but it reminded me of many tailgates where we bought the big pack of frozen patties and simply reheated and cooked them on a grill.

The service was good and fast.  The fries were decent, though nothing unique (also from a frozen bag?).  The bun was ok, and it came with pickle, onion and lettuce.  But it's still unclear if they made them there or used an external source for the patty.  

Bottom line:  After tip, I paid $12 for a burger, fires and coke.  There was no "wow moment."  If they produced something unique it might be worth it.  As it stands, I'd definitely recommend the place for other things, but not burgers. It's not their forte.
