I went back to SF last weekend for the first time after 4 years to attend a friend's wedding dinner. My other friends and I drove down to Downtown SF at noon just to checkout what's new.
We walked over to Chinatown for lunch. Most Chinese resturants in Chinatown are mediocre but R&G Louge located on Keary street has always been decent. Its house special, salt and pepper crab, is way better than any crab you would find in Fisherman's Warf.
