Inside the Park:
Probably the most unique characteristic of the ballpark is The Western Metal Supply Co. Building, a 100-year old brick structure, originally set to be demolished to make room for Petco Park. Instead, it was reinforced and updated to comply with current building codes, and today serves as the signature feature of the park, supporting the left field pole. Inside, you'll find the Padres Majestic Team Store on the first floor and on the fourth there's the Padres Hall of Fame Bar and Grill. Rooftop bleacher seating is available for groups on top of the structure, and the second and third floors offer private party suites you can rent.
On the Mezzanine Level beneath the Right Field Grandstand, you'll find The Power Alley - an entertainment area offering interactive games like a batting cage and fast pitch game. Also family friendly is The "Park at the Park" - a 2.7 acre area just beyond the outfield fence. You'll find a Little League Infield, kids' play area, picnic area, and you can even purchase cheap tickets and watch the game from there.
There's a cool sand area beyond the right field fence called "The Beach." You can watch batting practice from there pre-game, but once the game starts, it's reserved for Bleacher ticket holders.
Food and Drink:
There's a pretty good variety of concessions inside. You won't have a problem finding traditional ballpark fare at stands like Friar Franks (multiple locations) or K Street Grill. On the Field Level near Section 108, there's the Mercado which includes a variety of local food like Anthony's Seafood Grotto where you can get items like Fish and Chips or Clam Chowder in a bread bowl, and Randy Jones BBQ for some really good pulled pork.
One of our favorites in San Diego is the Fish Tacos found at any Padres Mexican Cafe. If you're only going to try one thing at Petco - that would be it. There are some new concessions for 2011, and one of the most popular is Filippi's Pizza (multiple locations), serving up cheese, pepperoni, and veggie pies.
For the health-conscious fan, there's Friar Fit (Field Level Section 101) which has a variety of healthier items including Sushi, and there's Veggie Burgers at Bay View Grill and Veggie Dogs at Friar Franks. (multiple locations). In addition, there's a new Gluten Free stand on the Field Level near Section 104.
There are also a few sit-down restaurants inside. We love Baja Bistro (terrace level) for a pre-game meal. Great shrimp tacos and Carnitas plate - plus they serve alcohol until the end of the game. (most others stop at the end of the 7th). Or stop by Club 19 on the Terrace Level. They have a really interesting (albeit not cheap) menu, serving up items like Beef Short Rib with Bacon Bread Pudding, Caprese Salad, and a Chorizo Sausage Corndog. They also have a full bar. For a different bar scene, hit up the Hall of Fame Bar and Grill inside the Western Metal Supply Building and grab a jalapeño hot dog wrapped in bacon and a few beers.
Another favorite is Westwinds, a sushi restaurant with a cool view of the field. When the attendance is below 30,000, they're open to the public, otherwise it's just for Terrace Level ticketholders. They also serve alcohol until the game is over.
There are a couple of Ballpark Brew Stands (Field and Upper Levels) offering over 20 different beer options. Behind the Mercado on the Field Level is La Cantina Bar - an outdoor full bar specializing in margaritas.
Seating:
Petco Park offers some of the best standing-room only tickets around. There are several standing room rails around the concourse, and the views aren't bad. In the Field Pavilion, there's All You Can Eat seats for roughly $30, which is good choice if you plan on dining on just standard fare like hot dogs and soda.
The "Park on the Park" is a pretty great deal at only $5. If you buy these $5 park passes try to then stop by the Hall of Fame Bar and reserve a table on the outdoor patio with a much better view of the game. You can get a table for the beginning of the game until the end of the 3rd inning or one from the 4th until the end of the game - and enjoy a great view for cheap.
