You can POWER WALK to Taco's de Juaez from downtown (I'd only suggest it during the day though)
Not Tee Pee and not sure about the other places.
Don't discount Carolina's Mexican Kitchen- also POWER WALKING distance from downtown- great Chimichanga's!
There have been ton's written on here about Phoenix eateries. Suggest using the search function and you'll find lotsa places. If you want specifics, give me more info and I'll try to help you. Sounds like you'll be here after baseball season starts. Chase Field, home of the Diamondbacks, is in downtown if you want to catch a ballgame.
Foodbme, you da' man (or woman -- I don't know you). Anyhoo, two quick additional questions:
(1) Have you ever eaten at Old Pueblo Cafe in Litchfield Park? (I've got AZ friends who rave about the place and such may be my first dinner in town.)
(2) And what are the decent if not regional food offerings at Chase Field (where the Diamondbacks are, indeed, playing a pre-season game while I'm in town)?
I'm a Guy last time I checked!
I've heard of Old Pueblo Cafe but never been there. I checked a bunch of reviews on the place and here's a synopsis. Sonoran style food which means Burritos, Enchaladas, Tacos, Salsas.
Most people thought the price was right. Food rated from average to above average. Some said not flavorful enough. Family friendly. Pretty good Margaritas and most all liked the Salsa & Chips. Service generally good. Karioke at night and some other entertainment. Atmosphere was fine. Should be good for a casual gathering with Friends. A few Margaritas and you'll be doing the Mexican Hat Dance!
Another place I'd highly recommend is the Wigwam Resort in Litchfield Park. It's very close
to the Old Pueblo. It's the FIRST resort ever built in the Phoenix area. It was recently purchased by a group that includes Jerry Colangelo, former owner of the Dbacks & Suns. They did $7 Million in renovations and it's a beautiful example of Desert Resort living. JRPfeff and his wife recently stayed there and they loved it. They have excellent restaurants there, both upscale and casual and definitely worth a visit if only for a drink (Or two!) and to see a beautiful Western Resort. http://www.wigwamresort.com/
On to the Old Ball Game!
You mentioned you would be here for a pre-season game. They hold their Pre-season games at their new training facility up in Scottsdale. It's brand new and rated as the Best training facility in MLB. They Share it with the Colorado Rockies. Here's the web site. http://www.saltriverfields.com/
It was built on an Indian reservation. There's a Casino, restaurants and hotel nearby for food & Drink. If you are here after the season starts then the games will be downtown at Chase Field. http://arizona.diamondbacks.mlb.com/index.jsp?c_id=ari
Suggest you check your and their schedules to be sure I give you places at the right venue. Report back please!
