this little place is just behind the sports facilities (swimming pool and velodrome) at can coix. there is a bus service to it these days and some taxi drivers may even know where it is. i wouldn't recommend walking to it.
the directions are from the centre of san an take the road (calle ramon y cajal) past the football stadium and keep going, you'll pass sa capella on the right. or coming from i-town make a right on the big roundabout on the tree lined avenue into san an and again keep going.
you know that it's only a little local place - no pretensions, not posh, but just really good food? regretably, every time i've been i found it closed!
