POCO "cold meter sequence" and panel

Our POCO wants cold sequence for a 400amp 3 phase to a coffee shop. Cold sequence is feed a disconnect, then the meter and on to the panel. We have an outdoor enclosure with a 400 amp breaker which feeds the meter. Then underground 25' to the panel in the coffee shop. 230.82(3) (2014) talks about this (I think) and calls it a "meter disconnect, not service equipment". The question is can that breaker be the service disconnect with all grounding out there and a main lug panel inside? Or should there be a main breaker panel inside the coffee shop. (Also the POCO will be locking access to the breaker outside.) The engineer drawing has a main lug panel inside and all the grounding originating in there, (rods, water, ufer), which definitely doesn't seem right, and just a #3 going out to the main enclosure. Thanks for input.
 
We have been required to have a disconnect ahead of the meter since 1980. It was confusing at first, IE who owns it, but we typically use a non fused disconnect and the POCO locks that, its not considered the disconnect. If you can't use a non fused, and have OCPDs, then your lock goes on the disco and its a service.

interestingly, this practice was not recognized by the NEC until a few code cycles ago

Could you expand on where in NEC this is discussed ?

There was another thread discussing the issue of the fact that a Non-fused disc has only a 10k SCCR. Hopefully everyone is taking this into consideration when installing these.

230.82 shows they can be installed ahead of the service equipment

Received an answer. We will install a main in the panel making it first means of disconnect and the outdoor breaker is the meter disconnect.

As far as grounding, 230.92 will require it be bonded. 250.24 would allow you to connect your grounding electrode conductor there but I would clear that with POCO 1st.
