I can't find the post where we discussed eating alone, which I do all the time since I travel so much.
Last week I must say that I had poor service at Alfredo's, Akershus, and Whispering Canyon. In each case the restaurant was half to almost empty, lots of servers around. I waited and waited while tables around me had service - at Alfredos the manager actually came over b/cause I had been sitting so long without a server ever coming over or offering me even a glass of water.
I must admit that it is not usually so bad (and I had lunch this week at Akershus with their usual excellent service)
However some servers cant seem to distinguish between discreet service and ignoring a guest. I like to read during my solo meals, but I still want service in a timely fashion.
My best/most consistent solo experience is the lounge in the Japanese pavilion - but the servers there are usually not young students, and seem to be permanent rather than on a temporary assignment.
