tortilla chips tossed in Sriracha.

friends and family!

whole wheat pasta arrabiatta.

Lucky Charms. I can eat a whole box in a couple of days. It's sick and wrong.

Champagne!

Definitely rent a car. Public transport is non-existent and it's like 100 plus degrees.
There are a few vegetarian restaurants, but maybe stick to places like Feast, Cup Cafe, Maynard's, Bluefin, Jax Kitchen, or J Bar. They all offer delicious food and service that will accommodate a vegetarians dietary needs.

We ate there on a whim while visiting the area. Just walked by and decided to stop for a light meal. We really liked it. The food was really comforting, but creative. Everything was well prepared and flavorful. We thought the wine list had a lot of unique options that didn't break the bank and the service was very friendly and casual.
I'd go back if we were in NY again. I wouldn't go as a special occasion stop though, just a fun casual meal.

Zinc Bistro is not very good. It's poorly made, wanna-be French food. Sauce is OK, but it's a chain.
Pizzeria and Pane Bianco are excellent. You will wait for Pizzeria Bianco, but if you get there early, it's not too bad.
St. Francis is new and very good.
Cowboy Ciao has a chaotic but incredible wine list and is a classic for the area.
Gallo Blanco in the Clarendon Hotel downtown is great modern Mexican. Fantastic tacos.
Matt's Big Breakfast, for breakfast obviously.

I agree with Mizzvenuz, and say head to Tucson. Much better weather, and really far more interesting and creative restaurants to choose from. Especially if you want real Mexican Food. Plus Tucson is more down to Earth, and friendly than the Phoenix area. It's only a 2 hour drive.

Tofu and brown rice. Dressed up according to my mood.

How about a "Trust Your Importer" tasting?
Then you can have various styles, producers, regions etc., but all brought in from one particular Importer. There are so many reputable importers, it could be very interesting to focus on one company.
Most of your fine wine shops would be able to accommodate such a tasting. You might not be able to accomplish this if you buy wines from a big box store, or a local grocer.

My husband is the bread baker in our house, and so far, each loaf gets better everytime he makes it.

I'm a better cook than most of our local restaurateurs are.
Bragging, but true.
Sorry.
