We walked for so long, asked a dozen people and finally reached Frank's. I was happy to have arrived here for the simple reason that I ended up writing two reviews on the way. A beautiful area hosts hundreds of sweet parlors, pastries and sandwicherias, pubs and more that tourist guides don't tell you about.
Frank's has the famous honey rainbow cake and the long rainbow cake roll. Purple, blue, green, yellow, orange and red on top with two colorful slices on the inside. My expectations were high; sweet, honey aromas, spongy and watery, it has the feel and taste of commercial cakes. Not my kind of stuff, with a load of heavy cream and unneeded sweetness. Honestly, if I were to compare it with the rainbow cake I had at Doré Doré, the other one is way better.
The place is nice, beautifully decorated both from the inside and outside, yellow facades and lots of flowers many of which are dried and hung upside down from the ceiling.
I loved the coffee and how hot water is mixed with two shots of concentrated espresso to create the Americano. I personally wouldn't put it on Seoul's list of best cakes, though.
