I have to report a happy addition to the dearth of 4th Avenue in Northern Slope. Mule, the new coffee house on 4th Ave btween Bergen and St Marks is quite nice. Good, strong coffee, nice Serendipity tea, pastries from Ceci-Cela, very nice space and great garden, although with just one big table more appropriate for a italian wedding than strangers sharing coffee. The owner is very nice, and the well AC'ed room has been very pleasant these days to read. He says they'll start serving lunch soon- for now, it's filling quite a void.
