Sure there are plenty of foodie sites online like Yelp, Zeer, Dishola and tons more. But how many have actually merged into the iPhone space, the most portable way to figure out what you want to eat?

Here are 20 some food-related iPhone apps, both free and paid, that will let you eat your heart out:

Where (free)

A location-based app that works with Yelp as well as Starbucks. So you can find food and your coffee wherever you are. The app also works with GasBuddy (for the cheapest gas nearby), Eventful, Buddy Beacon, ZipCar, and Quibblo Quizzes.

Yelp (free) – The Yelp app is GPS-enabled and will find you places to eat nearby (amongst other things). The problem with this app is that it lacks Yelp’s best feature – the ability to review.

UrbanSpoon (free) – A fun app if you’re close to a city. It’s not as limited as the LocalEats app (above), but you’re not going to find anything nearby if you’re more than 20 miles from a city. It’s a slot machine application that lets you pick how much you want to spend or what kind of meal you want to eat. You shake the iPhone and it gives you a list of results within the categories you selected.

iFob (free) – This app goes against GPS technology and encourages Wi-fi connections. So when you’re at a restaurant that has wi-fi, you can walk away with a friend? The idea is to connect people that are within close range of each other. So maybe you’ll have an eating partner.

Restaurant Nutrition (free) – The most disturbing of the nutrition fact iPhone apps is this one. It lists the nutrition facts for most popular chain restaurants. You won’t believe how many grams of fat are in a chicken caesar wrap at Chili’s.

iWant (free) - A (possibly better) version of the Where To app (below) that’s free. Like the Where To app, it works easily like the POI navigation on a GPS device. Easy to use, easy to drive with. It has 3.5 stars at the iTunes store with the biggest complaint being that it doesn’t list enough results under some categories.

Nearby (free) – Works like other geo-locating apps, you search for things around you; only this time there will be various types of commentary about a particular spot: photos, notes, reviews and “virtual graffiti”.

YPMobile (free) – When worse comes to worse, hit up the Yellow Pages.

Where To ($2.99) - This is a cool little app that works like the POI (point of interest) function on a regular GPS. It finds your location, you choose a category, and it finds all of the places in that category that are near you. Food & Drink is just one of the 600 categories that you can choose from. It works kind of like a front-end to Google Search, however makes using it while on the road very easy and simple to use. Is it worth the $2.99? Well that’s less than a tank of gas in most places, so sure.

LocalEats ($0.99) – Based on the site wherethelocalseat.com, this app gives you the best 100 restaurants in the top 50 U.S. cities. The interface is extremely easy to use and it mostly avoids chain restaurants. The downside is that it’s only applicable if you’re near or in a big city. Still has 4 out of 5 stars at the app store.

Munch ($0.99) This amazing iPhone app finds restaurants according to your location. All restaurants are organized by food type for easy search-ability. Great for quick-launching searches for pizza, Mexican, and so on from icons in the screen navigation. Munch returns wonderfully accurate search results, but is devoid of context. There are no reviews, no Web site listings, and every restaurant we looked at was rated with five empty stars. That’s doable if you want a listings app, but for anyone trying to make intelligent choices, it just won’t work.
