Hobbits may be dwarflike creatures who like to eat a lot, but they’d be hard-pressed to get their mouths around the avocado buffalo burger ($8.79) at the Hobbit Cafe (2243 Richmond, 713-526-5460). There is simply no elegant way to eat this mammoth burger, whose large lean buffalo-meat patty comes on a whole wheat bun with field greens as well as all the traditional fixins. But what makes it extra-special is the one-inch layer of velvety-smooth smashed avocado, which sits atop the patty and oozes out with every bite. Served with chips or seasoned french fries, this burger is anything but dwarflike.
