The Peninsula is finally getting a chance to see what all the presidential fuss is about. If the enthusiastic response to the newly opened Burlingame location of Five Guys, President Obama's favorite burger spot, is any indication of the first family's popularity, the president should have no trouble in November.

At prime meal times, seats can be at a premium, although an efficient staff cleans tables quickly to keep the chaos under control. Lines to order can be long, too, but the staff keeps those moving. And there are bushels of free peanuts to munch on while you wait.

Choices are straightforward - a hamburger (plain or with cheese or bacon, in two sizes), a hot dog (plain or with cheese or bacon), grilled cheese sandwich and a veggie sandwich made from the vegetable toppings.

Five Guys' claim to fame: All the toppings are free - and there are plenty of them, from mayo and ketchup to grilled onions and mushrooms, hot sauce and jalapenos.

The other claims to fame? There's not a freezer in the place - everything is made to order daily, and portions are large.

The 700-calorie count posted for the hamburger ($4.99) might give some pause, but that covers two patties for a total of about 8 ounces. A single-patty hamburger ($3.89, 480 calories) is plenty for normal appetites, and nicely done, with crisp bacon on the bacon version ($4.69).

A regular serving of fries ($2.89) - the provenance of each day's potato is listed on a chalkboard - is more than enough for two. Fries are cut wide enough to turn out creamy rather than crunchy, so if you want super-crisp, ask or you'll be disappointed. You also might be let down if you leave the burger in its foil wrapping too long - the bun gets soggy.

What isn't disappointing, however, is the kosher-style dog ($3.79). It's split and grilled, and tucked into a toasted bun. Don't know if that's one of the presidential favorites, but it's a sure winner nonetheless.

Five Guys Burgers and Fries: 203 Primrose Drive, Burlingame. (650) 343-3016. 11 a.m.-10 p.m. daily. No alcohol. Other locations in Hayward, Fremont, Dublin, Sunnyvale and San Jose.
