There are less expensive lunches, but everything in the menu is not exactly cheap (not overly expensive either though). Salads, noodle and stuff, rice and stuff, soups with and without noodles, a lot of various food. Not at all as expensive as Loving Hut in Moscow (when it was open), but has no Western food either (enjoy your sweet soup for desert, for you can't find a cake or, say, tiramisu here). I guess if you are used to eating in Loving Hut in your country or wherever, visiting this one might be completely different. Various hot and cold beverages.
But all the advantages it has are crossed by its location. It's an hour or so ride on LRT from KL center and then two kilometers if not more of walking/riding taxi. Unless you live somewhere nearby, I don't suppose anyone will spend a couple hours and RM10-20 just to get to the place where you can eat (probably it's more reachable if you have a car, but I'm not sure). There are a lot of places everywhere else, after all.
I actually liked it, but I won't probably ever be there again.
(Also, I'm not sure, but it seems that location on the map is not exactly correct although the street is right so you will find it eventually anyway.)
(Also2, they actually accept credit cards now although I couldn't pay with my card because of some technical issues.)
Cons: location, not cheap, almost no Western food
