We just completed our third tour with Taste It Tours and we've been impressed with all of them.  All 3 tours are distinct and are loaded with excellent restaurants.  I've spent quite a bit of time downtown, but it can be daunting and I haven't ventured much to explore and try new things.  The tours take you to the places you may not notice as you whiz by, give the history (yes Phoenix has history), and overall just slow you down to take in the sights, sounds, and of course, food!

Can't decide which tour to take?  Start with the Original, then the warehouse and finally the evening.  Really, they're all good!  

Tips: Have a light snack before starting the tour.  Yes you do get a lot of food, but keep in mind that the tours start at 2pm or 6pm.  You have introductions, overview, some history and then a short walk to the first restaurant.  If you're skipping lunch, you might be very hungry when you arrive as the first restaurant.  2) Wear comfortable shoes.  You will be walking about 2 miles.  Nothing strenuous or fast paced, but just be conformable (also wear comfortable clothing as you will get full).  3) Pace yourself!  Don't eat everything that is in front of you.  Each restaurant gives a fair amount of food, now multiply that by 3+ more restaurants that remain on the tour...You get the idea.  You will be full!  

Highly recommend for anyone: locals, out of town visitors, guests of locals, team building, etc.  Really, who doesn't like food!

Side Note: Taste it Tours was founded by a few Phoenix locals who love food and their city.  They have only been around about a year now and have been doing extremely well.  They base their business around supporting local businesses (local supporting local).  I'm excited to see how well they've done and wish them all the best (More tours are in the works and I will definitely be taking them!)
