As a general rule, if the network is flat (one VLAN), and you have basic connectivity, DHCP will work. So long as the users are in the same broadcast domain as the DHCP server they should be able to acquire addresses from it.
1) It depends on how you are connected to your ISP and also what kit you are using to connect your remote sites.
2) Following on from 1) i suspect that the ISP cloud will route your traffic to the HO. In that case you will not be able to have a flat network structure. There are ways around this such a VPLS, L2TPv3 etc.
L2TPv3 you can configure if your devices support it, VPLS is a provider solution.
However it would be a lot simpler to simply create a separate subnet for each remote site on your DHCP server. And then if you are using a Cisco device at the remote sites under the LAN interface on each device
The further advantage of using separate subnets is that it will be easier to keep track of who is doing what on the network.
Thanks for your reply. Each restaurant is going to have a 877 installed. So you are saying that on the dhcp server I will create 4 different scopes 192.168.1.0,2.0,3.0 & 4.0. Then on the each restaurant on the E0 or F0/0 interface I will configure ip helper-address 192.168.2.1 for restaurant 1, then restaurant 2 ip helper-address 3.1 and so on.
