I have had a chance to try LAMILL two times now and found some good and bad.
First of all, the room is very well done. Not my style, but executed well, comfortable, and efficient. I wish there was some more bar space because it's hard to take a table by oneself and not feel uncomfortable. Which is the first problem. The layout, style and service are geared towards a restaurant more than a coffee "boutique." The linear arrangement of tables and formal table service make this a hard place to go and simply relax and hang out. This may be their plan however.
Second, who knew so many upscale people were in Silverlake? I have been to all the places in and around, and this is the first time I have seen such a gathering of well heeled locals. There does seem to be a market here. I have read that other posters regard this as pretentious or out of character, but to me it's a natural progression much like Venice, or West Hollywood, or Soho.
Third, the food. Well... I had high hopes, but in my two trips both items have been bad. The ABLT sandwich was average at best with little flavor. The banana bread was a chewy cupcake with hardly a hint of banana. The menu is limited but supposedly it will be expanded soon and I still think it has potential so I'll try again.
Fourth, the service. It's slow. Everyone is very nice and helpful but our table service took about twenty minutes from ordering to get two sandwiches, and my service at the bar when I was the only one there took almost ten minutes before anyone took my order. Apparently not everyone working at the bar is able to take an order (a bit frustrating.)
The price? Not bad depending on what you order and your expectations. A banana bread and cup of coffee $5.95 pre tip. Two sandwiches and tea service about $40.
Then there's the coffee. I had the clover with a dark roast which was not on the menu and it was perfect. Not a hint of bitterness, just pure flavor. This was the best cup of coffee I may have ever had, and it will keep me coming back. I am going today in fact, and I hope there's a seat at the bar.
