The full 5 star package5/5

Sfish57 · 2020-10-19 · value 5/5 · build 5/5

One of the best sets I've come across in a long while. My first modular building set and definitely won't be my last. Love the micro and macro details. Building the set is fun and each new section is different, even if some the structures are the same. Playability also high with all the little details in each room. Truly impressive. Also looks amazing as display piece. I appreciate the compactness of the build even w

My new favorite modular5/5

indykid · 2020-07-03 · value 4/5 · build 5/5

Only my 5th modular set but this one is so versatile and has so many possibilities for play/display that I don't think it's a leap to say it's the best, or at least the best one I own. Overall it's definitely a great set for the 10th anniversary of the modular buildings and has some really neat easter eggs/references to past sets including 2 big ones for Cafe Corner (my first modular set). It's definitely a very rewa

The Essence of Nostalgia for any Modular Building fan5/5

The Ideal symbol of any city: I started my journey of constructing a Lego city a little over fifteen months ago. It began with the 2018 modular building Downtown Diner. I loved every aspect of this series of buildings and wanted all of them. My research of various buildings culminated in the discovery of the most eye-catching Lego set of all-time, Assembly Square. Something about this model told me that I needed to h

That is a lot of building5/5

DutchFlyer · 2018-05-04 · value 5/5 · build 5/5

Summary This is the first modular set I bought, and I am extremely pleased with that decision. Some 8,5 to 9 hours of building fun, with many clever techniques on display. That said, it nowhere comes close to the 'outlandish' feel that I got when building Ninjago City. The construction sequence does a nice job of preventing one from the build becoming a drag, as does the addition of some details.There is a ton of det

A wonderful set to cap off the first 10 years of modular buildings5/5

Zapp_Brannigan · 2018-01-13 · value 5/5 · build 5/5

When modular buildings first came out, I was in my early teens, which meant that requesting such sets as the Cafe Corner for my birthday or Christmas would be downright impossible, obviously because of their size and price. Fast forward ten years, and I'm at that point in my life where "adulting" is slowly beginning to take its course. In other words, with the small bit of income I earn as a grad student, I was able

Maybe life has been getting to me a little too much these days and Lego is losing it's magic to me but I can't help but feel disappointed with this set. It is a lovely set but there is something missing. maybe I'd have enjoyed it more if it the numbered bags didn't just reach 8, maybe it is that it has numbered bags and highlights every piece on every page, one of my true pleasures with Lego was playing spot the diff
