I went two times to this coffee shop only cause it's in the market area where after half day of shopping you really feel the need of sitting and refreshing yourself. After all, you will find here the less hassle of an outdoor area where you can serve something around Khan el Khalili. The first time did not impress me in any way. Poor service, having daily consumed by locals items at tourist prices and with lots of mobile vendors (can't avoid it since it's actually located in a passage of the market). The second time visited it at the insistences of friends and had realized they overcharged us the first time.(they actually have inside a card with the prices if you can read Arabic). The service even worse, with waiters who do not look at you, leave you to wave for minutes and take your drinks before you could even consume half. Three servers came to take the tea pot and glasses away and we had to stop them every time. You could clearly see that the evening is approaching and they wanted to liberate the 'couch' who could accommodate more than 3 of us.
Would really recommend the Naguib Mahfouz restaurant where, even if you sit indoors and the prices are higher, you can have a better service, better atmosphere and a really nice, traditionally decorated place. Can serve food and definitely better done items. Full of history too, as it can tell the story of Egypt's most important writer.
If you are not that eager to rest in Khan el Khalili and have a little more time, indulge yourself in one of the less frequented by tourists quarters where at every corner you will find a local coffee shop raising in a garage, with the same old style chairs and tables and where most probably a better tea with mint / karkadee / lemon juice and shisha would cost you around 1 - 1.5 EUROs (as a tourist).
