i used to go regularly to ons huisie, but had a very dreadful experience there today. after very bad service, we tipped the waitor 5% to signal him that we were unsatisfied (he messed up our order, not once checked on our table, and when asked about something to clean my fingers after some prawns, he said he would bring it, bumped into some friends outside and never brought it). so far, so normal, happens every now and then. but the waitor actually followed us to our car outside and barked at me about being undertipped. i have never seen something like that and it make me feel very uncomfortable. very disappointing experience. food was ok and luckily the great views are free, even if you don't go to the restaurant!
