We just moved offices and landed near the Tempe Cornish Pasty Co. It's certainly an office favorite. There is very limited seating so we usually go before 11:45 or after 1pm if it's a lunch rendezvous. The food is amazing and unless you're from the UP, chances are you haven't had anything like it. There are a ton of different pasty options. Every time I look over the menu, it's like Christmas all over again.
Service can be a tad slow, but I realize that perfection isn't pre-made. The beer selection is outstanding as well. The staff is solid, very polite, and usually showcase a nice selection of body ink. Don't be scared to try some apps or lighter fare. EVERYTHING there is great.
Also, they offer half cooked Pastys. So you can swoop in grab them and finish cooking at your leisure. Although I usually like posting up a the bar and taking in the great crowd and atmosphere.
It's a weekly stop for me and I don't see that slowing anytime soon. I also frequent the location in Mesa (corner of Dobson and Guad). It's a much larger location with a slighty more upscale feel. Same great food and service.
