The Landmark is a good diner. After all, Guy Fiere has eaten here (Food Network: Diners, Drive-Ins, and Dives). The food is standard for what you would expect. I had a western omelet, rye toast, bacon, coffee, OJ, and bacon. The coffee was amazing - which is key for a good diner. The rest of the food looked good but was lacking in flavor which was disappointing. I am going to chalk it up to an off day or maybe what I ordered.
The house favorite seems to be the French toast. I missed out this round but next time it's on! Seriously, people rave about how good the French toast is. Also, I've got to try their deserts. They look out of this world and are made on site at a bakery they have in the basement of the Diner. In fact, I may just go for desert and coffee sometime.
As for the rest of the experience, the service was excellent, the environment is perfect for a diner: clean, cozy, it just has that certain Je ne sais quoi. Despite being on Central Ave, the crowd is diverse in a way you will not feel out place. Also, people bring their kids (at least for breakfast anyway) so you can consider this a good family place. Now, at night that is probably another story as the night can bring out a different element.
As I had said, this is a good diner. I will be back soon!
